EDWARD TURNER, OF BALTIMORE, MARYLAND.

HAlVIE-FASTENING.

Specification of Letters Patent No. 11,501, dated August 8, 1854.

To all whom t may concern Be it known that I, EDWARD TURNER, ofBaltimore, State of `Maryland7 havel invented a new, and usefulFastening 'for Hames; and I do hereby declare that the same is describedand represented in the following specifications and drawings.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and use referring to the drawingsin which the same letters indicate like parts in each of the figures.

Figure 1, is an elevation of my improved fastening. Fig. 2, is a planand Fig. 3, a

section through t-he line .a e of Fig. 2.

In these drawings A is a curved piece of metal provided with a hook B atoneend, which hook is intended to be inserted in the ring upon the endof the hame and the end B of the hook bent down onto the recess C, andfastened by riveting soldering or otherwise. i v i The piece A has thegroove D in it to which the c urved rack or sliding piece E is fitted soas t0 traverse freely, Vand this curved rack is provided witha hook Fwhich is to be inserted into the end of the opposite hame and the end Fbent down upon the projection G and fastened by riveting soldering orotherwise.

The sliding piece E has a groove H in it, for the end of a springto behereafter de scribed, and upon each side of this groove H there areseveral inclined notches I I to receive the end of the pawl J which pawlmay be made in the form represented or otherwise and fitted to vibrateon the pin K which passes" through it and through `the cheeks L L whichproject from the piece A as represented for that purpose'.

The rear end of the pawl J has the bent i spring M riveted tofit theopposite end of the spring resting on the bottom of the groove I-I inthe sliding piece E. This spring allows the front end of the pawl to beraised, as the notches I I pass Linder it as the piece E is pushed inand when a notch passes in Closes and holds the piece E, in the piece A,very firmly thereby securing the ends of the hames together. Whenever itis desirable to separate the haines the rear end of the pawl may bepressed clown with one hand, and the piece E drawn out of the piece Awith the other. The sides of the cheeks and the bottom of the groove Dare beveled away, and the end of the piece E is chamfered off so that itmay be inserted between the cheeks with facility.

By my improved fastening a pair o-f hames may be connected and fastened,or disengaged with greater ease and in less time than by any otherfastening known to me whether it is done in the dark or light.

Another advantage in curving the fastening is that it may be opened andclosed without depressing the curve of the collar under it, therebyobviating the defect of straight fastenings, which do depress the curveof the collar under them whenever they are opened or closed. y

What I claim as my invent-ion and desire to secure by Letters Patent inthe above described fastening for haines is- A curved rack,. fitted totraverse in a groove provided With a vibrating catch operated by` aspring substantially as described.

In testimony whereof I have hereunto Witnesses:

THOMAS B. HAUGHTON, J. DENNIS, Jr.
